As a PSC motor manufacturer, it is prudent that you make fast decisions when one of your
clients is faced with comfort or failed motor compliantly. At times the best
decision that you have to make is not an obvious decision. This article will
discuss of some of the best and most popular technologies that can be used to
do PSC motor replacements.
It is crucial that you check the cooling and the heating
anytime you replace the motor blower. This is just to ensure that the blower
meets the OEM specification when it is installed in the new motor. The
installer should check if they conform to the temperature rise specification of
the furnace as it operates. He should also measure the flow of the air for
cooling and confirm that it is operating as per the manufacturer's airflow
specification. At most times the PSC motors are used when there is a need for
moderate electrical efficiency and when starting the torque requirements. They
are mostly used on gear motors, small pumps, blowers and on fans. These motors
have peak efficiency just like that of the AC induction motors. It occurs at a
point os speed between 5% and 10 % below the synchronous speed. The speed that
rotates the magnetic field from the stator winding is what is known as
synchronous speed. The PSC motors are designed in a way that it has many
speeds, and it only achieves the peak efficiency when it is at its highest
speed. If you use a lower speed like in the constant fan mode, then the motors
efficiency decreases drastically.
One of the variable speed electronically controlled motors
is the electronically communicated motors. They have the ability to control
frequency and current on the motor winding and this, on the other hand,
provides speed control and torque. Frequency and current control together with
the use of magnets enable the ECM to operate at an efficiency of 80%. Induction
motors can be made in a way that they can run at a single speed and be
efficient at the same time but, ECM motors have the ability to maintain their
efficiencies high across all the ranges of speed. The OEMs are enabling to work
with PSC motor manufacturers so as
to keep the efficiency and the comfort of the motors at their optimal place.
With the above knowledge in place, we would like to know the
replacement methods that we have. One tends to wonder if they should order an
identical original motor or they should contact the original manufacturer of
the motor. You can use stock replacement to substitute the failed motor. On the
other hand, you can also consider using the ECM motor to replace the failed
one. It the system you are using is still under warranty then it is
recommendable that you follow the warranty replacements.
If the customer is dissatisfied with the comfort, then you
can contact the PSC motor manufacturer
for a replacement. The producers will be willing to do the replace in the case
of inconsistent temperatures like it becomes too cold or too hot.
